sodium benzoate and vitamin c

Hi, I have read that when sodium benzoate and vitamin c combine they can cause carcinogens. Is this true? Could you apply them at different times and it be ok? For example, I use a retinol serum with sodium benzoate in it at night and then apply a sunscreen with vitamin c in it in the morning. Is this a problem?


  • We answered this question back in Episode 153. Here's what we said:



    The soft drink industry has responded by removing benzoates to a large extent although there are still products that use them. That’s enough background because this is not the Beverage Brains podcast.

    What does all this mean for Vitamin C creams? It doesn’t seem like this a problem in skin products for two reasons. First, benzene is a much greater health concern if you’re ingesting it which was the issue in the case of the benzene in soft drinks.

    Second, the product she mentions also contains EDTA which chelates metal ions and reduces the chances of benzene formation.Ref:
